This is only a four-year old washer, but it's barely agitating. It fills, drains, and spins just fine, but during the wash cycle, it just wobbles a little. Of course, the VERY friendly people at GE were willing to send a repairman out to my house for 70 bucks, but they couldn't give me any DIY help. Btw, I didn't purchase this washer, it was a gift when I bought my first house. I have five kids, so getting this washer running again soon is essential. Thanks!

Model # is correct. I had already removed the agitator, and although I can't tell whether it is the drive bell or not, it seems like a cheap and easy place to start. It also seemed to have a lot of gunk built up around the drive bell and under the agitator. I'm not sure if that's normal or not. I will follow-up. Thank you.

Odd, I get a hit on S1070A#WW where # = (1,2,4 or 5 but no 3) - ...moving on...

Pull the agitator, run a low fill cycle and see how the drive bell moves when in agitate. Carefully grab hold and see if it feels like it has a strong movement. If so get the drive bell & start washing again.

It does not seem to be the drive bell. All the splines (I think that's what you call them) are in good shape and not worn. I thought this washer was a belt drive, but upon inspection of the inside, it appears to be direct drive. When I pulled the drive bell and looked at it, then replaced it, I ran a small amount of water. It agitated strongly for a moment, then went back to barely agitating. Any other suggestions?

It is in fact a belt drive but since it spins fine I wouldn't think that was an issue. The failure of the drive bell is not from the spine to the drive bell but rather the drive bell to the agitator. You described it as more of a wobble that is why I was trying to see how the drive bell feels with the agitator removed. If it is weak at that point I would suspect a transmission failure.

One more thing to check, is the motor speed, is it in fast(normal cycle) or slow. Depending on the model some of the GE washers run slow then fast in some cycles.

The movement of the drive bell without the agitator seems strong, despite the fact that both pieces don't seem to have any undue wear. I'm going to replace that today and see what happens. I will follow up.
